Final answer:
Benito Mussolini came to power in Italy through electoral success aided by violence and fear tactics by his supporters. He was appointed prime minister by the king to prevent civil war and subsequently created a fascist dictatorship by suppressing opposition and controlling political power.
Step-by-step explanation:
The statement that best describes Benito Mussolini's rise to power in Italy is 'c. Mussolini came to power in an election, but voters were intimidated by the considerable violence that his followers demonstrated.'
Mussolini's rise involved strategically using fear and intimidation. He denounced the Treaty of Versailles and capitalized on Italy's discontent post-World War I. His party, the National Fascist Party, supported by the Blackshirts, engaged in violent tactics against opponents.
In 1922, during yet another government crisis, his march on Rome prompted the weak-willed King Victor Emmanuel III to appoint Mussolini as prime minister. After obtaining this position, Mussolini and the Fascists manipulated parliament, suppressed opposition, and created a police state, leading to a fascist dictatorship.
